About a year ago, Nvidia presented a novel head-mounted display that is based on light field technology and offers both depth and refocus capability to the human eye. Their so-called Near-Eye Light Field Display was more a proof of concept, but it’s exciting new technology that solves a number of existing problems with stereoscopic virtual reality glasses.
Nvidia researcher Douglas Lanman recently gave a talk at Augmented World Expo (AWE2014), in which he explained the background and evolution of head-mounted displays and the history and design of Nvidia’s near-eye light field display prototypes: Continue reading →
At this year’s SIGGRAPH conference, currently taking place in Anaheim CA, tech blog Engadget spotted an unusual participant in the “Emerging Technologies” section. Douglas Lanman and David Luebke from the research labs at graphics processing specialist Nvidia presented what may be considered a prototype of the future of Virtual Reality: a near-eye light field display.
But what does it do? Microlens arrays, which are mounted just in front of the high resolution displays, are used to convert pixels to individual light rays, thus creating a light field directly in front of the eye. The viewer is thus able to refocus at multiple depths into the scene.
